When the material cart 2 moves to the position of the elevator 3, the traction frame 122 connects the material cart 2 and drives the material cart 2 to move along the ground guide rail 121.

[0025] The material cart up and down line device 1 provided in this embodiment first guides the material cart 2 to the position of the elevator 3 through the guide member 11, and then drives the material cart 2 to move along the ground guide rail 121 through the traction frame 122, so that the material cart 2 completes the long-distance transportation; the traction frame 122 drives the material cart 2 to move under the elevator 3 and the elevator 3 interacts with the material cart 2. After the interaction is completed, the traction frame 122 drives the material cart 2 to move out of the elevator 3, so that the material cart 2 runs smoothly, so as to facilitate the material cart 2 to go online.

[0026] In this embodiment, the material cart 2 is used to transport materials to the production line, and the elevator 3 is arranged on the way from the material cart 2 to the production line. When the material cart 2 reaches the position of the elevator 3, the elevator 3 takes away a part of the materials on the material cart 2. The material cart 2 is driven by the traction frame 122 to move along the ground guide rail 121, so that the material cart 2 passes under the elevator 3. In this way, when the elevator 3 takes the materials from the material cart 2, the material cart 2 does not stop and runs continuously, so the material cart loading and unloading device 1 facilitates the material cart 2 to go online.

[0027] The ground guide rail 121 is arranged below the elevator 3 to reduce the floor space occupied by the material cart loading and unloading device 1 and facilitate the layout of the small material cart loading and unloading device 1.

[0028] In a possible embodiment, the guide member 11 includes a guide frame 111 and a pushing frame 113, the guide frame 111 has an online channel 112, the online channel 112 extends to the ground guide rail 121, one end of the pushing frame 113 is arranged at the middle of the online channel 112, and the other end is arranged at the position of the elevator 3, and the pushing frame 113 is used to push the material cart 2 to move along the online channel 112 to the position of the elevator 3.

[0029] In this embodiment, the guide frame 111 includes a first guide rod 1111 and a second guide rod 1112 that are spaced apart, and an on-line channel 112 is formed between the first guide rod 1111 and the second guide rod 1112. The trolley 2 enters the on-line channel 112 from one end of the on-line channel 112 away from the elevator 3, so that the trolley 2 can complete long-distance transportation. The first guide rod 1111 and the second guide rod 1112 are located at the end away from the elevator 3 and are in an outward-splayed shape, so that the trolley 2 plays a guiding role when entering the on-line channel 112, so that the trolley 2 runs smoothly, so that the trolley 2 can go online easily.

[0030] In one possible embodiment, a loading outlet 1121 and an AGV outlet 1122 are provided at one end of the online channel 112 close to the elevator 3. The material cart 2 is moved to the online channel 112 by an AGV trolley 4. The AGV outlet 1122 is used for the AGV trolley 4 to move out of the online channel 112, and the loading outlet 1121 is used for the material cart 2 to move out of the online channel 112.

[0031] In this embodiment, the material cart 2 is driven by the AGV trolley 4 to enter the online channel 112. When the AGV trolley 4 drives the material cart 2 to move to the middle of the online channel 112, the pushing frame 113 starts to push the material cart 2 to continue moving toward the elevator 3; the AGV trolley 4 separates from the material cart 2, and the AGV trolley 4 moves out of the online channel 112 from the AGV exit 1122. The material cart 2 moves to the loading outlet 1121 under the push of the pushing frame 113, so that the material cart 2 runs smoothly to facilitate the material cart 2 to go online.

[0033] In a possible embodiment, the pushing frame 113 includes a push rod 114 and a linear motor 115, and the push rod 114 is rotatably connected to the linear motor 115. When the linear motor 115 moves in a direction away from the elevator 3, the push rod 114 can be forced to rotate to avoid the trolley 2. When the linear motor 115 moves in a direction close to the elevator 3, the push rod 114 can resist the trolley 2 to push the trolley 2 to move.

[0034] In this embodiment, the linear motor 115 is spaced apart from the upper line channel 112, and the push rod 114 is rotatably connected to the linear motor 115. A tension spring 116 is provided on one side of the push rod 114, and a stop block 117 is provided on the other side. One end of the tension spring 116 is connected to the end of the push rod 114, and the other end is connected to the linear motor 115. The tension of the tension spring 116 causes the push rod 114 to swing toward the stop block 117. The push rod 114 stops rotating when it contacts the stop block 117. One end of the push rod 114 is provided on the linear motor 115, and the other end protrudes toward the upper line channel 112.

[0035] When the AGV trolley 4 drives the trolley 2 to move toward the elevator 3 in the online channel 112, the AGV trolley 4 drives the trolley 2 to the position of the push frame 113, and the trolley 2 resists the push rod 114 and rotates in the direction away from the stop block 117. The AGV trolley 4 drives the trolley 2 to continue to move. When the trolley 2 is separated from the push rod 114, the push rod 114 receives the elastic force of the tension spring 116 and moves toward the stop block 117 and stops at the stop block 117. The linear motor 115 drives the push rod 114 to move toward the elevator 3, so that the push rod 114 pushes the trolley 2 to continue to move in the online channel 112. Therefore, the trolley 2 does not stop when moving in the online channel 112, and runs continuously, which is convenient for the trolley 2 to go online.

[0039] In a possible implementation, the traction frame 122 includes a clamping jaw 123 and a moving member 124 . The clamping jaw 123 is disposed on the moving member 124 . The clamping jaw 123 is used to clamp the trolley 2 . The moving member 124 moves the clamping jaw 123 to drive the trolley 2 .

[0040] In this embodiment, the trolley 2 enters the ground guide rail 121, the clamp 123 clamps the trolley 2, and the moving part 124 moves the clamp 123 to drive the trolley 2 to pass under the elevator 3. When the elevator 3 takes the material from the trolley 2, the trolley 2 does not stop and runs continuously, so that the trolley 2 can go online.

[0041] In a possible embodiment, the moving member 124 includes a rack 125 and a servo motor 126. The rack 125 is spaced apart from the ground guide rail 121. One end of the rack 125 is provided on the guide member 11 and the other end passes through the elevator 3. The output shaft of the servo motor 126 is engaged with the rack 125. The clamp 123 is connected to the servo motor 126. The output shaft of the servo motor 126 rotates to drive the clamp 123 to move along the rack 125.

[0042] In summary, the material cart up and down line device 1 provided in this embodiment first guides the material cart 2 to the position of the elevator 3 through the guide member 11, and then drives the material cart 2 to move along the ground guide rail 121 through the traction frame 122. The material cart 2 moves under the elevator 3 and the elevator 3 interacts with the material cart 2. After the interaction is completed, the traction frame 122 drives the material cart 2 to move out of the elevator 3, so that the material cart 2 runs smoothly to facilitate the material cart 2 to go online.
